Volume snapshot recurring schedule not showing

[ernjvr]

Description

In the UI, when Setting up a recurring snapshot for a volume and clicking 'Add', the newly added scheduled snapshot entry is not displayed in the 'Scheduled Snapshots' table. Also, the 'Keep' input field does not limit the length of a number that can be added. This causes the API not return an error that the value is invalid.

After adding a recurring snapshot, it must display in the 'Scheduled Snapshots' table. The 'Keep' input field must restrain a user from entering too large of a number.

How Has This Been Tested?

Manually

In the UI, click on the 'Instance' button. Click on an instance. Click the 'View Volumes' button. Click on a specific volume. Click the 'Set up Recurring Snapshot' button. Add a Recurring Snapshot and observe that it now does display the newly added schedule. Also when adding a 'Keep' number, it will limit the user to a maximum of 9 numbers.
